What is the meaning of  "Amen"?

The word Amen is a Hebrew word meaning "So be it" or "May it be". If  we say amen at the end of our prayer, we say: "May it be so." In other  words, may what we prayed or said in our prayer be manifested or fulfilled.  Jesus used this word often. He began many of his statements with "amen-amen"  meaning "Verily, I say unto you." The Good-News Bible translates it:  "I am telling you the truth." It means much more than just a full-stop  at the end of your prayer. Use it with the full meaning that was originally  intended!
